Enhance your material sorting efficiency and minimize downtime by equipping our flagship excavator with a waste package. This package is designed for optimal reach and engineered to improve machine stability.
- Designed to protect vital machine parts
- Improved protection from airborne debris
- Reduced wear on components
Product Features and benefits:
Auto Reversing Fan:
- Protect your radiator from damage caused by airborne debris with an auto-reversing fan. The manual switch allows for regular purging to keep the radiator clean.
Engine Pre-Cleaner:
- Ensure a clear engine by using a pre-cleaner that removes large particulates from the engine air, extending the air filter’s life.
Wide Core Cooling Package:
- Prevent debris accumulation and maintain airflow through the radiator, hydraulic oil cooler, A/C condenser, and charge air cooler with the wide core cooling package.
Cab Pre-Cleaner:
- Enhance air quality in the cab with a pre-cleaner delivering filtered air to the HVAC system. Pressurize the cab to reduce odors and extend the HVAC filter life.
Chassis Seal Package:
- Reduce debris entering the engine compartment by using a chassis seal package that shields vital parts.
Severe Duty Revolving Frame Under Covers:
- Protect vital internal machine components with 9-mm thick under covers for the severe duty revolving frame.
Corrugated and Perforated Screen Package:
- Increase efficiency and maximize open area with a corrugated and perforated screen package, promoting increased airflow to the coolers.
Radiator Cleanout Access Cover:
- Access the engine side of the radiator for cleaning through a removable cover with tethered knobs.
Operator Cab Guarding:
- Ensure cab protection with OPG level 2 top and front guards, available as bolt-on options to a base ROPS cab.
